Particular dealers:

• B&B Smith, Booksellers. ``A specialty bookshop trading primarily in new and used books on archaeology and classical studies.'' Excellent prices. You can email and get on their mailing list. In 2001 or 2002 they moved out of their long-time digs in Philadelphia and moved to more affordable space in the burbs. Everyone moaned about their wonderful memories from the old store.
• Liber Antiquus, Early Imprinted Books. Deals in editions of classical authors printed before 1700. (email Paul M. Dowling, Proprietor.) Physical location in NYC (hours by appointment). For serious collectors. (You can become a serious collector for what it costs to buy some new science textbooks.)
• Blake's Books ``[A]n online used and antiquarian bookstore. We carry a wide array of books for scholars and readers in all subjects, including art, philosophy, religion, math, science, history, literature and the humanities.'' (email).
• L & L Enterprises. ``Carries a large selection of materials for LATIN TEACHERS.''
• Bolchazy-Carducci On-line. (A publisher as well.) Reputation precedes it.
• Kalamos Books. Books about Greece, and books in Greek or translated from Greek. All periods.
• Greece In Print.
• Abelard. In Toronto. Funny, I thought he went to a French monastery after Heloise's father's friends did to him.
• Atticus Books. Another one in Toronto! A subthread at the time of the list discussion.
• Blackwells in Oxford. (Not included in searches on AddAll below.)

Search engines:

• AddAll is a meta search engine that searches bibliofind, and most other large used-book databases simultaneously
• Bookfinder.com -- ``a book shopping search engine that scans bookseller databases to find new, used, rare, and out of print books.'' Just don't type bookfinders.com by mistake.
• Bibliofind.com -- many millions of ``used and rare books, periodicals and ephemera offered for sale by thousands of booksellers around the world make this the most interesting book-selling site on the Web.'' Far superior to Amazon.com, but Amazon bought them in 2000, and they're starting to show the colors in April 2001.
• 21NorthMain.com -- ``[f]ind the used, rare, out-of-print, and antiquarian books you need here. Enter now and search for the volumes you want among the millions in our database.'' Hmmm, seems to be defunct in January 2003. Most significant web mentions I see of it are contemporary with this epinion from Summer 2000. The website also received a design award in May 2001.
• abebooks.com -- ``world's largest network of independent booksellers.''
• For European titles try NVvA search (from Holland, has English-language search form.)
• ZVAB (in German.)
